Right 4-Engel elements of a group
A. Abdollahi, H. Khosravi
We prove that the set of right 4-Engel elements of a group is a subgroup for locally nilpotent groups without elements of orders 2, 3 or 5; and in this case the normal clos…
When right n-Engel elements of a group form a subgroup?
A. Abdollahi, H. Khosravi
Let denotes the set of all right -Engel elements of a group . We show that in any group whose 5th term of lower central series has no element of order 2, $R_3(G)…
On the right and left 4-Engel elements
A. Abdollahi, H. Khosravi
In this paper we study left and right 4-Engel elements of a group. In particular, we prove that is nilpotent of class at most 4, whenever is any element and $b^{\pm…
Casimir Effect In Krein Space Quantization
H. Khosravi, M. Naseri, S. Rouhani +1
An explicit calculation of Casimir effect through an alternative approach of field quantization [1, 2], has been presented in this paper. In this method, the auxiliary negative nor…
